The consolidation of a powerful and vast high-pressure field over Central-Western Europe is literally dividing the continent into two large blocks.
The advance of high pressure up to subpolar latitudes, north of Great Britain, is allowing the descent of polar air masses over Eastern Europe and Scandinavia, where conditions are completely opposite to those in the western area.
Europe divided in two
In the west, the weather is stable almost everywhere, and temperatures are above the seasonal average; while in the east, especially between European Russia, Scandinavia, and the Baltic States, we find extremely lower temperatures and snowfalls at very low altitudes, even down to the plains.
As for Central-Western Europe, the only notes of bad weather are present in Spain, where a cyclone between Portugal and Southern Spain is still producing rains and local downpours after the floods of recent days.
Fortunately, this disturbance is dissipating, and in the coming days, high pressure will prevail again over the Iberian Peninsula.
Cold air in the east, what impact will it have?
The accumulation of cold air over Eastern Europe and Scandinavia could influence the course of the autumn season.
During this time of year, a real reservoir of icy air often develops over Eastern Europe, capable in the long term of modifying the general baric setup over the continent.
The arrival of polar currents over Eastern Europe and Scandinavia could therefore have repercussions both on the end of autumn and the start of the meteorological winter in the month of December. But what could happen in detail? The very low temperatures that day by day reach Eastern Europe could lead to a further weakening of the polar vortex, and the consequent expansion of high pressures over Western Europe.
In this way, the cold currents coming from the East could, in a retrograde movement, also reach the Mediterranean. This possibility could materialize at the beginning of the second decade of November, when a core of cool air coming from the east could impact the Mediterranean, causing not only a drop in temperatures but also a new wave of bad weather, especially in the extreme South.
